ONE TOOL, MULTIPLE SYSTEMS: Covers EVAP, turbo, intake, exhaust, vacuum, and fuel systems with dual-pressure modes (0.5–17 psi). The 19-piece kit includes an EVAP adapter, ready to use out of the box. Find leaks behind Check Engine lights, failed emissions, rough idle, poor gas mileage, and more.
BUILT-IN AIR PUMP: No external compressor required. Just connect to your 12V battery and start testing. Portable and self-contained, perfect for home garages, driveways, or mobile mechanics.
DUAL MODE (AIR + SMOKE): Air Mode pre-checks for leaks without wasting oil. Switch to Smoke Mode to pinpoint the exact leak location. Saves time, oil, and guesswork.
ULTRA-FAST, DENSE SMOKE: Dense smoke appears instantly, and the full leak detection process takes as little as 7 minutes — even on EVAP systems and long intake paths. Thick, visible smoke makes every leak easy to spot.
COMPACT, LIGHTWEIGHT & AFFORDABLE: Small enough to fit in your toolbox, yet powerful enough for professional use. Runs on baby oil for low operating cost, and helps avoid expensive shop diagnostic fees. Works on most 12V gas/diesel cars, SUVs, light trucks, motorcycles, ATVs, boats, and snowmobiles — ideal for DIYers and mechanics.
TRUSTED FOXWELL QUALITY & SUSTAINABLE DESIGN: Backed by FOXWELL’s 17 years of R&D and regularly tested on real US vehicles. Built with GRS-certified recycled materials for a lower environmental impact. A reliable, professional-grade tool you can count on.
